Situations that should be illegal:Sex with childrenEugenics - the concept of snipping various cords in the body to prevent someone from having children:child molestersrapistsseverely disabled/mentally handicapped peopleI have to write eighteen more words before I can post this message, now just five more words.

Only if it's consensual.

Because this is such a no-brainer question, I'm going to say yes.To begin with, sex makes messes. It also attracts serial killers and assorted monsters. Stay safe! Stay celibate!Also, most people have SEXUAL INTERCOURSE IN THE FORBIDDEN FOREST without a thought to consequences. People should know exactly what happens after sex and what they should prepare for if they do want to have their (illegal) sex. Cloning for the win, citizen. The Computer is your Friend.

Banning sex won't solve problems related to it. It would only make it worse.

When a person is not allowed to do things, due to some form of need to rebel, they would do it as much as they can. People would purposefully F*** in public just to spite the law and once caught they'd be treated no differently than that of a rapist or even a terrorist. Not to mention the many old sex crimes, such as rape increasing due to the urges going into overdrive. You could tie tubes, vasectomy and even chop it off, but while that would slow down the urges, they would have this empty feeling inside them that they will need to compensate through other means, such as murder. It is a known fact that male murderers alone, who have a history of sexual related problems, such as the common erectile dysfunction, use a knife to compensate for their lack of use of private parts, because both have been used to symbolically and literally penetrate the victim they would use said knife on. Not to mention the many new sex crimes one would invent in order to further enforce the law. Such as if one were to give another person Aids even by accident, it would be counted as murder since it's an incurable disease. Spreading other diseases would be a new form of assault. Hell I wouldn't be surprised if known terrorists such as Taliban and ISIS would up their game by dropping the chemical warfare in favor of cultivating all the known STDs in the lab due to it being counted as a crime so horrible that to use it would spread the fear. That being said, who would watch the watchmen. Surely the ones enforcing the law would probably put some kind of loophole or exemption that would prevent them from getting arrested should they themselves feel like F***ing to ease the stress of enforcing said laws. Meaning people are still gonna be having sex even if the law is against it. To make a long story short, banning sex isn't the answer. The only people that should be prosecuted are those that abuse their so called right to F***. Such as rapists, pedophiles, reproductive abusers and the like. More laws should be enforced on those specific crimes, not the act in general.

It's a part of life

There are 100% no logical or scientific reasons that having sex is not allow in this world, even god didn't say we cannot have sex, because it's a part of life, I mean this is how humans interact with each other, know how to work together, and save the bloodline of mankind. So it's 100% legal, whatever is it.

We need to embrace the natural parts of ourselves!

That is completely absurd. Sex is a completely normal and healthy part of life. Patriarchal society along with religion has demonized sex by making it seem as though it is some dirty thing that you can only do with one person in your whole life, which is so irrational. If you would like to know why priests abuse young children, you need look no farther than their unnatural vow of celibacy. The human body requires sex. The act of sex causes mental, emotional and physical release. It strengthens relationships. Not to mention, it creates new people (which is sort of essential to humanity!). Instead of demonizing sex, we need to stop making it out to be this secretive thing that only happens in the dark and just accept that it's natural, it's not dirty and that it's good for you. Only negative things will occur from going against nature.

Of course not.

It would be irrational to ban sex, why use other methods of reproducing if we have the best method right at our hand and provided by mother nature? There is no social reason to ban sex or sexual behaviour as long as its legal. Perhaps if the question was further defined it would make more sense.

I Don't see how That Would Work

Um would you like to be the last generation? Banning sex couldn't work because it's necessary for human reproduction. Besides, how would that ever be enforced without invading people's personal privacy? Or are we also banning that? I don't see how this could work at all. It could quite literally be the last thing people do!

Unless you feel like this being the last generation.

Humans could be reproduced in a lab, at a ludicrous expense. But in essence, the human race would be over. Without bulk, we humans are nothing. We were pretty far down the food chain before we started clumping together 70,000 years ago, we're not going to survive if we're in minute numbers.

Like you could even enforce it.

No for a few reasons. 1. The only alternative reproducing for humans is in a lab which excludes those who can not afford said methods.2. Sex is fun... Seriously, sex relieves stress on a huge scale and can help strengthen relationships.3. Enforcement would be ridiculous.4. 0 public support5. Loose termsThe list goes on.
